Hi,
I have a general question regarding the sediment flux output at a profile (f.e. 75009SHistory.dat).
The file contains of 6 columns, #1 = time, and the rest is sediment flux. I did not find anywhere in the manuals what these columns describe, can you give me information?
# cross_section-> 75009
# time sediment_flux_[m3/s]
3.0393264 0 0 0 0 0
3602.3912 0 0 0 0 0
7200.2858 0 0 0 0 0
10802.092 0 0 0 0 0
14400.009 0 0 0 0 0
18002.085 0 0 0 0 0
21600.108 2.012227035e-05 2.826660801e-06 1.729560955e-05 0 0
The last one is always zero.
I am running a model with 4 grain classes:
"MORPHOLOGY": {
"BEDMATERIAL": {
"GRAIN_CLASS": {
"diameters": [
4.0,
27.0,
55.0,
120
]
},
"MIXTURE": [
{
"name": "Gail_oben",
"volume_fraction": [
2.0,
28.0,
50.0,
20.0
]
},
{
"name": "Gail_mitte",
"volume_fraction": [
5.0,
45.0,
30.0,
20.0
]
},
{
"name": "Gail_GAP",
"volume_fraction": [
5.0,
30.0,
50.0,
15.0
]
},
{
"name": "Gail_Zugabe",
"volume_fraction": [
5.0,
25.0,
50.0,
20.0
]
}
],
"SOIL_ASSIGNMENT": {
"type": "index_table",
"index": [
1,
2,
3,
4
],
"soil": [
"Gail_oben",
"Gail_mitte",
"Gail_GAP",
"Gail_Zulaufstrecke"
]
},
"SOIL_DEF": [
{
"name": "Gail_oben",
"LAYER": [
{
"bottom_elevation": -2.0,
"mixture": "Gail_oben"
}
]
},
{
"name": "Gail_mitte",
"LAYER": [
{
"bottom_elevation": -1.0,
"mixture": "Gail_mitte"
}
]
},
{
"name": "Gail_GAP",
"LAYER": [
{
"bottom_elevation": -2,
"mixture": "Gail_GAP"
}
]
},
{
"name": "Gail_Zulaufstrecke",
"LAYER": [
{
"bottom_elevation": 0.0,
"mixture": "Gail_oben"
}
]
}
]
},
I am assuming, that the columns are the sediment flux up to the corresponding grain size given in the morphology block, and the last column is the sediment flux above the last grain size, but I do not find any confirmation in the manuals and want to confirm it before I start my analysis.
Thanks a lot,
Elisabeth
